The Lowdown
Alright, Rusty here. Let's look at what's on the table for the next couple of weeks.
To be straight with you, the outlook is a tough one for the paddle surfer. The whole 16-day window is a write-off for quality surf. There's not a single day where the conditions line up for a good session. From Wednesday, August 5th, all the way through to Thursday, August 20th, it's a consistent run of poor surf. The wind is locked in from the east-northeast, blowing a cross-shore breeze at 15 to 22 mph, sometimes even 25 mph, which just tears the surface up. The wave comment is "poor surf conditions" for almost every single period, with only a couple of days near the end of the second week (August 17th and 18th) even being described as "marginal".
The only spot in the mix is Kohala Lighthouse – a heavy advanced reef break. It's consistent, but it's exposed to the north, and the swell we're getting is from the ENE. The optimum swell direction for this place is from the north, so we're not even getting the right angle. The swell heights build through the period, starting around 4.3 ft and climbing to a solid 10 ft by the 18th. The combined swell energy gets strong, hitting values like 1529 by the 18th, but it's all for nothing with that cross-shore wind. The period is short, mostly 6 to 9 seconds, so it's a jumbled, weak windswell, not a clean groundswell. The water temp is about average for the time of year, but you won't care about that when you're fighting a lumpy, choppy mess.
The only flicker of hope is on Monday, August 17th afternoon and Tuesday, August 18th, where the swell gets up to 8 ft to 10 ft from the ENE, with a period stretching to 9 or 10 seconds. The energy is strong (1138 to 1529), and the comment shifts to "marginal". But it's still cross-shore at 22 mph, and the break quality is poor. This is big, powerful, and messy – strictly for experts only if they're desperate. It's the best of a bad bunch, but it's not a standout. Honestly, the whole setup with that much wind and that kind of swell at a beach setup would look more interesting for kite surfing than paddle surfing.
Hang in there, but don't hold your breath. This is a blank run.

Information about the Kohala Lighthouse Surf forecast
The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
